7 '0 all w]: am it may concern Be it known that I, WAL'rnu O. AMsLnn, of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and nseful Improvements it;

0 which the following is a specification.

My invention relates to a new and improved coin controlled vending-machine, designed to be operated to deliver articles by the insertion of a coin of predetermined denomination.

The embodiment of my invention as illustrated by the accompanying drawings, relates more particularly to a vending-machine designed to deliver small quantities of bulk materials, such for example as candy, from a magazine supplied therewith. My invention. however, is not limited to a machine for vending small quantities of ma-' tcrial in bulk, for it is within the scope of the invention to provide a machine capable of delivering articles in packages or boxes and articles of considerable size.

An object of the present invention is to provide an efiicient and simple vending machine particularly free of a complicated mechanism for preventing the operation of the machine when an improper coin or other article is introduced into the apparatus.

A further object of my invention is to provide means for coupling certain parts by the action of a proper coin whereby the articles may be delivered to the discharge opening of the machine.

A still further object is to provide a construction inw-hich the article-deliverymcmber ot' the machine and the coin-carrierincmber coact in sizing a coin.

In the accompanying drawings, which illustrate an application of my invention, Figure l, is a vertical sectional view of a vending-machino constructed in accordance with my invention, having its base and magazine broken away; Fig. 2 a plan with the magazine removed; Fig. 3 a View similar to Fig. 2, with upper plate removed; Fig. i a plan similar to Fig. 3, but showing some of the parts in a different position; Fig. 5 a perspective view of bottom-plate; Fig. 6, a perspective view of coin carrier member; Fig. 7, a similar view of article delivery member; Fig. 8, a detail view of a portion of the base; andFig. 9, a perspecfor locking the parts.

magazine signed to contain the materials tive view of a portion of a band employed.

or articles to be vended, and 2 a base.

These parts maybe of any desired form and construction.

Located below and designed to support the magazine is a stationary circular plate 3. hers 4C projecting upwardly from a bottom plate or member 5. Each of the lates or members 3 and 5 is provided wit a contrally disposed opening through which a small threaded axial bolt 6 is passed.

cured to the lower end of bolt 6 by means of a nut 7 is an article delivery chute 8, and located between the head of bolt 6 and the upper face of plate 3 is a ring 9.

- interposed between the upper and lower stationary plates and separated from each other by a ring or washer 10, I employ two rotary lates or members 11 and 12. Plate or mem er 11 is designed to pass or deliver Plate 3 is mount-ed on two upright mem;

a measured amount of the contents. of the magazine to the discharge chute and will be hereinafter referred to as the article-delivery-plate or member. This article-deliverymember or plate is formed with an opening 13 adapted to normally register with an opening 14 formed in the plate 3. Opening 13 is bounded by a depending flange 15 and forms, with said flange and the stationary plate 5, a pocket 13 of just sufficient size to contain the desired quantity of the material to be vended.

Plates 11 and 12 are each respectively connected with plate 3 by coiled springs 16 and 17 and are each provided with holes enabling them to be journaled on the stud or an upwardly extending ange 21 ocated on of the base porthe curved outer edge of plate ormember 12. The coin receiving and coin carryin member 12 is provided with an actuating fiever or thumb-piece 22, and in addition thereto, with means for sizing a coin. The sizing means on member 12, which coijperate with the article-delivery-member11 in sizin an form to the corresponding cross sectional dimensions of the proper coin, thereby preventing coins or other objects whose dimensions exceed that of the proper coin from being introduced to the opening. The

proper coin is guided into and held in operative coupling position by the members 23, 24 and 25, coacting with the article-delivery-. member and after being laced in the desired position it engages t e coin engagingmember 26-on member 11 thereby couplin the members 11 and 12 and allowing sai members to be moved in unison in the operation of delivering the contents of the pocket 13*- into the discharge chute through an opening 27 formed in the lower statlonary plate 5. Should a coin of smaller dimensions than the proper coin be placed in the coin receiving opening, it will fail to come into contact with the engaging-member 26 Q of member 11 and the said movable membars 11 and 12 will not be coupled together. After the insertion of the proper coin, which cou les the members 11 and 12 as above descri (1 said members are moved together in a curvilinear direction by means of the lever or thumb-piece and against the tension of their respective springs until the pocket 13 comes into register with the opening 27. Durin the travel of the two movable plates the coin is forced under a sprin -catch 28 mounted on and projecting throug the top plate 3. The function of said catch 28 is to 7 release the coin from the coin carrier member 12, or from between the two members 11 and 12. In order to accomplish this function the parts are so arranged that upon a return movement of the movable-members, due to the action of their respective springs catch 28 will strike an edge of the coin an prevent it being carried back with said movable-members. After the release of the coin from between the members it will drop into member 11 and stationary member 5 is formed with a slot 30 in which an end of spring 17 travels. Member 5 is also provided with a stop 31 to arrest'the travel of member 12.

Top-plate 3 is supported by the base-portion 2 and for this purpose I provide the top-plate with lugs 32 and form in the base a series of bayonet-like slots 33 adapted to receive the lugs 32.,

The magazine as illustrated comprises a lower contracted base portion 34 and is locked in position on its supporting plate by means of a locking-band Lockingband 35 is provided with a number of inwardly projecting members 36, particularly shown in Fig. 9. These members comprise curved portions 37 adapted to project through the slots 33 of the base and engage the contracted base of the magazine, as shown b Fig. 1. Members 36 are also provided'with flanges 38 ada ted to engage portions of the walls of the s ots 33.

The ends of the-locking-band are provided with apertured lugs 39 designed to project throu h a slotted washer 40. After the band 1s placed in positionits ends are locked or secured by a suitable lock, not shown.

To prevent the operation of the machine by a coin or other article of less thickness than the proper coin, I form the sizin member 23 inclined as shown. The inclination of this member together with the member 11 forms a wedge-shaped space, thus prevent ing a coin of less thickness engaging the" member 26 and coupling the parts.

What I claim is:

1. In a coin controlled vendin machine, a rotary spring controlled artic e delivery member, having a depending lug, a rotary spring controlled co'in carrying member parallel to the article delivery member and having upwardly projecting lugs coacting with 7 coin to pass inwardly a greater distance and escape engagement with the depending lug.

2. In a coin controlled vending machine, a rotary spring controlled article delivery member having a depending lug, a rotary spring controlled coin carrying member parallel to the article delivery member having an upwardly projecting lug for defining in connection w th the underside of the article delivery member the thickness of an operating coin, a lug having a vertical face for moving said coin into operative position, and a third lug having an inclined face whereby a coin or like disk of the correct diameter but of reduced thickness will be carried by the aforesaid straight faced lug past the depending lug of the article delivery member, said lugs when a coin of the proper thickness and diameter is inserted between them look said rotary members together to cause the delivery of the article to be vended.

3. In a coin controlled vending machine, a coin carrying member having themon a coin carrying lug, a coin advancing lug, and a lug formed with an inclined face;

4. In a coin controlled vending machine, a rotary spring controlled article delivery member having a depending stop lug thereon, and a rotary sprin controlled coin carrying member provide with an upwardly projecting advancing lug, a coin supporting lug adapted to define in connec tion with the article delivery member the thickness of a coin, and a lug having an inclined face to permit the advancing lug moving a coin'of insuficient thickness inserted between said members, out of engagement with the depending sto Inga,
